When batteries go bang as electric cars charge: Insights from a cyber security perspective. The image above shows an incident captured by CCTV in my own back garden earlier this year. This occurred when a power drill battery, which was being charged by builders working on my house, exploded and shot in the air. Fortunately, no-one was injured and no damage was done, apart from some slightly scorched grass. The lithium-ion battery in question was a branded product that had apparently been purchased from a reputable retailer. So why did it explode in such a spectacular way?
